Authentication

First use triggers OAuth authorization flow:

1. User is redirected to Delta to authorize
2. Tokens are stored encrypted per-user
3. Automatic refresh handles token expiration

No API key required — connector manages OAuth flow.

Find Delta flights from LAX to JFK on March 25th for 2 passengers

Check flight status:

What's the status of Delta flight 1234 today?

Book with miles:
